摘　　要：研究了以铸造废砂为填料、废旧地膜为基体,制备复合材料的界面问题。用加热—振动的方法可有效地除去覆盖在铸造水玻璃废砂表面的大部分惰性膜;用偶联剂进行表面改性后,可在不同程度上提高铸造废砂-废旧地膜复合材料的强度。提出并验证了制备铸造砂-地膜复合材料的有关工艺参数。The interface of the composites made of waste foundry sand as fillers and waste mulching films as matrix was studied. The most inert films covering the surface of waste sodium silicate-bonded sand for casting could be removed effectively by heating-vibrating method. The strength of the composites made of waste foundry sand and waste mulching films could be increased in varying degrees after the surface of waste foundry sand was improved by coupling agent. The relevant process parameters for preparing the composites made of waste foundry sand and waste mulching films were proposed and validated.
